    libxl: limit support for specifying an interface script
    
    Generally, <interface> ... <script> is only supported for
    type='ethernet'.  Due to the long and pervasive use of
    
      <interface type='bridge'>
        ...
        <script path='foo'/>
      </interface>
    
    in Xen domain configuration, it was agreed to allow the use
    of <script> with type='bridge' for backwards compatibility.  See
    the following discussion thread
    
    http://www.redhat.com/archives/libvir-list/2013-April/msg00755.html
    
    This patch limits the use of <script> to interface types ethernet
    and bridge, raising an unsupported config error if <script> is
    specified for all other interface types.
    
    While at it, use VIR_ERR_CONFIG_UNSUPPORTED instead of
    VIR_ERR_INTERNAL_ERROR when reporting unsupported interface types.
